Low-Profile Oil Cooler Thermostat for LS Engines

Improved Racing's low-profile oil cooler adapter bolts directly to the factory GM LS oil pan and features a built-in thermostat. The angled front cutout and a maximum thickness of just 1.30" makes this unit slim enough to clear most headers.

Oil coolers help prevent the oil from getting too hot, but are also prone to lowering oil temperatures too much, especially in colder weather or during highway driving. This unit's built-in thermostat helps protect the engine by speeding up warm-up time and maintaining oil temperatures at optimal levels. The thermostat maintains a minimum oil temperature of 180°F (82°C), 200°F (93°C) or 212°F (100°C) +/- 5°F in most conditions.

The adapter features an 1/8" NPT port for an oil sensor or turbo oil supply. It's machined from a single piece of 6061-T6 aluminum and is black anodized. The adapter features standard female -08AN O-ring boss ports for optional anodized adapter fittings for -08AN, -10AN or -12AN lines. The adapter can be mounted upside down on the 2010+ Camaro / G8 oil pan for additional header clearance.

Old part number EGM-1012.

Features and Benefits

100% bolt-on in place of the factory oil bypass cover, just above the oil filter

Note: This oil adapter is designed for O-ring boss fittings with a straight thread length of 0.500" or less. We recommend using our fittings in order to guarantee proper fitment and seal.

Corvette motor mounts: We recommend using a 90-degree AN fitting on the top port and a 90-degree AN fitting on the front (angled) port to connect the oil lines to this adapter.

F-Body motor mounts: We recommend using a 90-degree AN fitting on the top port and a 60-degree AN fitting on the front (angled) port to connect the oil lines to this adapter.

Gen IV LS Engines: On some engines, the knock sensor is located above the oil cooler adapter. To clear the oil cooler lines, you may need to loosen and rotate the knock sensor slightly, and unbolt and move the knock sensor wiring harness out of the way.

NOT suitable for front-sump pans such as Pontiac GTO or Holden/Vauxhall Monaro & Commodore oil pans. Please see our front sump oil cooler adapter for these applications, part number EGM-107.

This side mount oil cooler thermostat was the exact one I needed for my supercharged 425 ls3. Great quality and everything I needed for installation.

This was the only adapter I could find that would fit between my oil pan and 2-7/8" headers on my 2005 CTS-V. Tried a couple other options and just couldn't make them work. Great product with excellent packaging.

Great looking product, you can tell it's of high quality,
Fitted up perfectly to my engine with no dramas, and clears the exhaust on my FC RX7

Cheers

Thanks again for the great products, both this adapter and the strut bar are really top notch. I have installed this adapter without removing the JTR headers. The headers are also rapped so there is like almost 0 room to work. Obviously I preinstalled the AN fittings and hoses.
The temp sensor had to come off , then just a little wiggling, fiddling and a touch of persuasion and it fit right into place.
Then the gods must have loved me at that moment cause the o-ring, slid right into place the first attempt while balancing precariously on a finger

Anyway to the point

one allen bolt goes in no problem but the other is really tight and you can not fit an alen key in. So what you do is cut like 2/3 of an inch off your 5mm allen key then use that with needle nose vise grips

Installed easily like any other block. Clears JTR LT's in an FD with 1/4" to spare. Works well.
